- Test concentrations with justification for top dose:
- 33.3, 66.7, 100, 333, 667, 1000, 3333, and 5000 μg/plate
A correction factor based on the percent solids was used for preparation of the dosing concentrations. - Vehicle / solvent:
- - Vehicle(s)/solvent(s) used: Sterile water.
- Justification for choice of solvent/vehicle: Based on the solubility of the test substance and compatibility with the target cells.
Due to evidence of bacterial contamination of the test substance in the first toxicity-mutation test a 100 mg/mL stock solution was prepared in ethanol (ETOH) and allowed to age for approximately 30 minutes prior to formulation with sterile water. This method formulated a top dose of 50 mg/mL that contained approximately 30% ETOH and formed a clear pale amber solution. Each lower dose level contained proportionally decreasing amounts of ETOH. The negative control used on this study was a 30% ETOH solution prepared in sterile water to approximately match the amount of ETOH in the top dose level.

- Details on test system and experimental conditions:
- METHOD OF APPLICATION: The plate incorporation method was applied. Treatment without activation was conducted by adding 100 μL of an overnight culture containing approximately 10E9 bacteria per millilitre to top agar supplemented with L-histidine and D-biotin or L-tryptophan. The components were mixed and poured onto a plate containing minimal agar. Treatments with activation were conducted as those without activation except that S9 mix was added to the bacteria/top agar mixture before it was poured onto a minimal glucose agar plate. The plates were incubated at approximately 37±2°C for approximately 51 to 69 hours.
DURATION
- Exposure duration: 51 to 69 hours
NUMBER OF REPLICATIONS: The mutagenicity test was conducted 2 times. In the initial trial (E-1) the negative control values for WP2uvrA in the presence of S9 activation were outside the acceptable range. This condition was retested in the second trial (E-2). The data collected for WP2uvrA in the presence of activation in trial E-1 is considered invalid and is not included in the study report. - Evaluation criteria:
- For the test substance to be evaluated positive, it must cause a dose-related increase in the mean revertants per plate unless observed at the top dose level only. Data sets for tester strains TA1535 and TA1537 were judged positive if the increase in mean revertants at the highest numerical dose response was ≥ 3.0-fold the mean concurrent negative control value (vehicle control). Data sets for tester strains TA98, TA100 and WP2 uvrA were judged positive if the increase in mean revertants at the highest numerical dose response was ≥ 2.0-fold the mean concurrent negative control value (vehicle control).
- Statistics:
- For each selected tester strain, the mean number of revertants and the standard deviation at each concentration with and without S9 activation were calculated.

- Additional information on results:
- In the toxicity-mutagenicity test, test substance precipitation was observed starting at 3333 μg/plate for all test conditions with the exception of TA1537 in the absence of S9 activation where precipitation was observed starting at 1000 μg/plate and for WP2uvrA in the presence of S9 activation where precipitation was observed starting at 667 μg/plate. Two types of precipitation were observed in the mutagenicity test: a microscopic precipitation that was consistent with the precipitation observed in the toxicity-mutation trial, and a precipitation that appeared as a subtle change in the appearance of the top agar that was visible to the naked eye. The microscopic precipitation was observed for all conditions in the top two dose levels. Test substance precipitation was observed as a change in the appearance of the top agar in the absence of S9 activation starting at1000 μg/plate for TA1357, and 667 μg/plate for TA98, TA100, TA1535, and WP2uvrA; and in the presence of S9 activation starting at 667 μg/plate for WP2uvrA, and 333 μg/plate for TA98, TA100, TA1535, and TA1537.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative in the absence and presence of S9 activation
The study and the conclusions which are drawn from it fulfil the quality criteria (validity, reliability, repeatability).
Negative when tested in Salmonella typhimurium strains TA 1535, TA 1537, TA 98 and TA 100 and in Escherichia coli WP2 uvr A in the absence and presence of S9 activation. - Executive summary:
The test substance was evaluated for mutagenicity in the Bacterial Reverse Mutation Test using the plate incorporation method. Salmonella typhimurium strains TA98, TA100, TA1535, and TA1537 and Escherichia coli strain WP2 uvr A were tested in the absence and presence of an exogenous metabolic activation system (Aroclor-induced rat liver S9). The test was performed in 2 phases. The first phase was the toxicity-mutation test, which established the dose range for the mutagenicity test, and provided a preliminary mutagenicity evaluation. The second phase was the mutagenicity test, which evaluated and confirmed the mutagenic potential of the test substance. Based on the toxicity-mutation test, the maximum dose evaluated in the mutagenicity test was 5000 μg/plate. The mutagenicity test was conducted in two trials. WP2 uvr A was retested based on invalid negative control values in the first trial. In the initial toxicity-mutation test contaminating colonies were observed on the sterility plates for the most concentrated test substance dilution (50 mg/mL). The test substance was decontaminated with ETOH prior to use on any of the subsequent tests and no other contaminating colonies were observed.
No positive mutagenic responses were observed at any dose level or with any tester strain in either the absence or presence of S9 metabolic activation. No toxicity was observed at any dose level with any tester strain in either the absence or presence of S9. Two types of precipitation were observed: a microscopic precipitation that was consistent with precipitation observed in the toxicity-mutation trial, and a precipitation that appeared as a subtle change in the appearance of the top agar that was visible to the naked eye. The microscopic precipitation was observed for all conditions in the top two dose levels. Test substance precipitation was observed as a change in the appearance of the top agar in the absence of S9 activation starting at 1000 μg/plate for TA1357, and 667 μg/plate for TA98, TA100, TA1535, and WP2 uvr A; and in the presence of S9 activation starting at 667 μg/plate for WP2 uvr A, and 333 μg/plate for TA98, TA100, TA1535, and TA1537. All criteria for a valid study were met. Under the conditions of this study, the test substance showed no evidence of mutagenicity in the Bacterial Reverse Mutation Test either in the absence or presence of Aroclor-induced rat liver S9. It was concluded that the test substance was negative in this in vitro test.
